Oh nice one, that's kinda cool
See I thought the curie temperature was a 'one and done' sort of deal where you have to go through the process of remagnetizing the magnet after it had gone beyond that point.

Not sure where they said they "did an entire presentation on this thing" or where they got their information from. I'm only adding some context to what I know of how thermostats work. I would gladly admit I'm wrong if provided with some evidence.
If you want a visual demonstration of a thermostat working here's a video.
(For context I don't mean to come across as one of those "well ackshually" asshats, I just like watching people take apart electronics (was also slightly obsessed with magnets as a kid. MANY hard drives were sacrificed to my curiosity lol).)
https://en.m.wikipedia.org/wiki/Curie_temperature I doubt they're using magnets, especially considering how hot they have to get to lose their magnetism as you suggest.
Most thermostats in electronics such as kettles and cookers use a bi-metallic strip inside, where the two metal layers expand at different rates. The contacts in the switch are physically pulled apart by the strip bending when the desired temperature is reached. https://en.m.wikipedia.org/wiki/Bimetallic_strip
Ahh that makes a lot more sense
Cheers for the clarification
